Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what assessment she has made of the effectiveness of the Domestic Solid Fuel Regulations 2020.

In November 2025, we published the Post Implementation Review of the Air Quality (Domestic Solid Fuels Standards) (England) Regulations 2020, which assesses the effectiveness of the Regulations.

Data suggest that the Regulations have led to consumers moving from more polluting fuels to less polluting fuels. The review concluded that this has led to a reduction in emissions of PM2.5 and SO2 with environmental and public health benefits.
